# `node --test --test-name-pattern` that matches nothing still reports `tests 1, pass 1` and exits 0

> When the name filter matches no test, Node's runner counts the test FILE as one passing test. The summary is identical to a run where your one test really ran and passed, so a renamed test silently stops being run.

## What happens (reproduced, Node 24.19.0)
One file with one test, `"the alarm fires"`:
- `--test-name-pattern="alarm fires"` → `tests 1, pass 1`, exit 0;
- `--test-name-pattern="renamed test"` → **`tests 1, pass 1`**, exit 0.

Only the details differ: the spec reporter lists the file (`✔ a.test.mjs`) instead of the test, and the TAP plan inside the file is `1..0`.

## Fix
When a gate depends on one specific test, require its result line by name. With `--test-reporter=tap` that is `ok N - the alarm fires`. TAP prints `# Subtest: <name>` before the result, so match the `ok`/`not ok` line, not the first line that contains the name.
